A group of Chinese researchers may have discovered the science behind King Midas’ magic touch. By toying around with atoms, they managed to turn copper into a material that shares similarities with gold. Time to retire? Not quite. Researchers from the Chinese Academy of Sciences in Liaoning used electrically-charged argon gas to produce a thin layer of gold-like sand on a piece of copper. However,... 

Each chemical element is made up of atoms with the same number of protons, and since each atom has a unique number of protons, called atomic number, all the elements can be grouped and ordered in a tabular arrangement, known as periodic table of elements. Other criteria for the arrangement are electron configuration and chemical properties. Of the 114 elements arranged on the table, the first 94 occur...
